高强度人类活动对地球系统产生全方位的深刻影响，干旱已经不再是严格意义上的自然灾害，人类活动对干旱形成发展过程的影响是当前国际干旱研究的热点。本项目将综合利用水文气象观测及多源遥感观测数据，采用统计分析、遥感分析及分布式水文模拟的手段，系统分析不同流域自然地理条件与人类活动条件下（主要是水利工程调节与各种形式的用水耗水）的流域水文干旱特性以及气象干旱向水文干旱的传递特性，揭示水文干旱特性——干旱社会经济影响——水资源调控措施之间的相互作用机理，模拟不同水资源供需情景下不同水资源管理措施与干旱应急管理措施作用下的水文干旱形成发展过程，及其对不同用水行业、不同区域社会经济的差异性影响，在此基础上建立降低干旱影响、增加干旱应对能力的区域水资源调控方法，为变化环境下的抗旱减灾与最严格水资源管理制度实施提供决策依据。

In the Anthropothene when the earth system is profoundly affected by human activities, drought is no longer really a natural hazard. Anthropogenic impacts on the formation and propagation of drought becomes a hot issue in the international drought research community. The project will comprehensively use hydrometeorological observations and multi-source remote sensing observation data, and use statistical analysis, remote sensing analysis and distributed hydrological simulation to systematically analyze the catchment hydrological drought characteristics and the propagation from meteorological drought to hydrological drought under different geography conditions and human activities (mainly water conservancy engineering regulation and various types of water use and water consumption), so as to reveal the interaction mechanism between hydrological drought characteristics, drought socio-economic impacts, water resources regulation measures, and simulate the effects of different water resources management measures and drought emergency management measures on the development process of hydrological drought in different water resources supply and demand scenarios, as well as the effects on different water sectors and different regions. On the basis of above analysis, a strategy of regional water resources regulation and control methods and the best practices of drought emergency responses will be developed to reduce the social-economic impact of droughts and increase the drought response capacity, which be help to provide decision-making basis for drought control and drought disaster mitigation under the changing environment and for implementing the most stringent water resources management policy in China.
